1.25" C/S (1-1/4") (31.75 MM)

APG stocks the 02841250, a black Buna-N (Nitrile) 70 Shore A O-Ring Cord Stock measuring a cross section of 1.25 mm (0.049 in). An o-ring cord stock eliminates long lead times on large-diameter custom rings.

Expect good resistance to propane and butane, hydraulic fluids, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer.

Maintenance and OEM teams specify it across fluid power, construction equipment, and hydraulic and pneumatic systems.

Stocked as 02841250 and sold by the foot. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
